GS1000G - Carb Jetting

[KEITH KRAUSE]

OK. Been away on vacation and I've missed a lot. I thought I read that you had 1/3 to 1/2 throttle position problems besides a too large main jet for a stock bike? If I remember correctly, you had a jet kit (or adjustable needles from Canada) and it seemed they were set too rich. I'll try to help if needed.

Seems we are ok at the minute thanks Keith.
The needles may be rich but certainly not hugely so, with the new K&N inbox they seem about right. When I put the 115's in I think that should be about perfect, maybe a 117.5 because of the ethanol in the fuel here......

More of a question is the pilot circuit, it won't run with less than 3 turns on the screws. Very strange. Anyway, I'll be looking at it all as soon as possible & will give you a shout if I need any help. During normal usage the plugs don't look too bad. Interestingly Nessism who lives local to me also needs 3 turns on his 550! Strange huh?

I'm not sure why your bike needs the mixture screws set to richer than normal settings. Your very first post, where you mentioned what the mechanic did to the carbs, has me wondering why he did those things.
Typically, excessive mixture screw adjustment would be a form of compensation for poor fuel flow or a semi-blocked pilot circuit passage somewhere.

Weird huh.... I guess without tearing it down I probably will never know!

I guess I could seafoam it....

Bring your bike to me and I'll dip your carbs. Bring an o-ring kit from Mr. Barr. Plus you can get your windshield.\\/

I might take you up on that.... Might need new airbox boots too I guess. I'm going through a crazy month at the moment but I might get to you in October.

Cheers,

Dan
